\subsection[sec:imgRwFunc]{圖像讀寫函式}

對\reftab{imgReadFunc}、\reftab{imgReadWithoutSamplerFunc}
和\reftab{imgWriteFunc}中所列的圖像讀寫函式做了擴充，
以支持型別為 \cldt{half} 的圖像顏色值。

\placetable[here,split][tab:imgReadFuncHalf]
{內建圖像讀取函式}
{\input{chapter_optext/tbl/img_read_func_half.tex}}

\placetable[here,split][tab:imgReadWithoutSamplerFuncHalf]
{內建無採樣器圖像讀取函式}
{\input{chapter_optext/tbl/img_read_without_sampler_func_half.tex}}

\placetable[here,split][tab:imgWriteFuncHalf]
{內建圖像寫入函式}
{\input{chapter_optext/tbl/img_write_func_half.tex}}
